Key Broke Off in the Lock? Here’s What to Do
It always happens at the worst moment — a key snaps and half of it stays behind in the lock. Your first instinct will be to fish it out with whatever’s handy — but what you do next determines whether this is a ten-minute fix or a ruined lock. Here’s what to do, in order. Stuck right now?

Broken Key in the Lock: What Not to Do
When a broken key is stuck in a lock, the worst move is pushing harder. Glue, super-thin pliers and repeated jiggling usually drive the broken key deeper or jam the pins, which turns a quick extraction into a full lock replacement.
If you can see the end of the broken key, gently try a pair of needle-nose tweezers with the lock in the unlocked position. If it doesn’t slide out easily, stop. The Associated Locksmiths of America recommends calling a trained professional, who can use proper extractor tools and cut a new key on the spot.
First: Stop and Don’t Force It
A broken key is a mechanical problem, and force makes mechanical problems worse. Jamming the remaining half in, twisting harder, or wiggling aggressively can push the fragment deeper, bend it inside the cylinder, or damage the pins — turning a simple extraction into a lock replacement. Put the broken piece down and check: is part of the key still sticking out, or did it break off flush?
What NOT to Try
Some internet advice will wreck your lock. Avoid these:
- Superglue on the broken end. The classic bad idea. If the glue bonds to anything besides the key fragment — the pins, the cylinder wall — you’ve just glued your lock shut. Professionals don’t do this, and neither should you.
- Jamming in random tools. Paperclips, nails, and pocketknife tips can bend pins or wedge the fragment tighter. The inside of a lock is precise; it punishes improvisation.
- Drilling the lock. Drilling destroys the cylinder. It’s a last resort for a locksmith with no other option — not a first move for a homeowner. Once drilled, the lock must be replaced.
How to Get a Broken Key Out of a Door Lock: Safe DIY Methods
If enough of the key protrudes to grip, you can try this — gently:
- Needle-nose pliers or tweezers. Grip the protruding fragment firmly and pull straight out along the key’s normal path. No twisting, no yanking at an angle.
- A broken key extractor tool. These inexpensive hooked tools slide alongside the fragment and catch it. If you don’t own one, this is the moment that justifies the few dollars.
- Lubricate first. A squirt of powdered graphite or silicone-based lock lubricant reduces friction. Work the fragment gently — if it doesn’t move with light pressure, stop.
Light pressure only, one or two careful attempts — if it doesn’t move easily, it needs professional tools.
When to Stop and Call a Locksmith
Call when the fragment is flush with or inside the lock face, when gentle attempts haven’t worked, or when it’s a car ignition or high-security lock — those have tighter tolerances and less room for error. Also call if the lock was already stiff or the key was visibly worn; there’s a good chance the lock itself needs attention, not just the fragment removed.
A locksmith extracts broken keys with purpose-made tools that grip the fragment without touching the pins — usually in minutes, without damaging the lock. After extraction, the broken pieces can be used to cut you a new key, so bring both halves. Our key duplication page explains how new keys get made from originals or fragments.
How to Keep It From Happening Again
Keys rarely snap without warning. They give notice:
- Replace worn keys before they break. If a key is bent, cracked, or visibly thin at the stress points, get a copy made from the least-worn key you have — copies of copies degrade. Duplicating early is cheap insurance.
- Don’t use keys as tools. Prying, scraping, and box-opening flex the metal and create micro-fractures exactly where keys snap.
- Keep locks lubricated. A yearly shot of graphite or silicone-based lubricant keeps the cylinder smooth, so you’re never tempted to force a stiff key.
- Fix stiff locks promptly. A lock that fights you is stressing every key you put in it. If lubrication doesn’t free it up, have it looked at before it eats another key.

Frequently Asked Questions
Can the broken piece be used to make a new key?
Yes — in most cases a locksmith can cut a new key using the broken pieces as the pattern, provided the cuts are readable. Bring every piece you have.
Will extraction damage my lock?
Professional extraction shouldn’t damage anything — that’s the whole point of the specialized tools. DIY attempts with force or glue are what damage locks.
How much does broken key extraction cost?
It varies with the lock type and situation — a standard house door is a quick job; a car ignition takes more. Our locksmith cost guide explains how this kind of work is typically priced.
The key broke in my car’s ignition — is that different?
Yes. Ignitions have tighter tolerances than door locks and the fragment is harder to reach. Don’t attempt DIY extraction on an ignition; call a locksmith or your dealer.
Should I try pushing it through from the other side?
No. Pushing from the back usually wedges the fragment tighter and can damage the pins on the way. Extract from the side it entered.
I’m locked out because of this — now what?
If the broken key has you stuck outside, treat it as a lockout: don’t damage the door trying alternatives. Our lockout guide covers what to do while you wait for help.
The Bottom Line
A broken key is a small problem that becomes a big one only through force, glue, or drills. Try the gentle methods once if the fragment is reachable; otherwise, let a locksmith’s extractor tools do in minutes what frustration can’t do at all.
